Hi there,
I want to fill a Hidden Field on an aspx page after clicking a link.

My Code:

01.

<%@ Page Title="Home Page" Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebApplication6._Default" %>

02.<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

03.

04.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

05.<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

06.<head id="Head1" runat="server">

07. <title></title>

08.</head>

09.<body>

10. <form id="Form1" runat="server">

11.

12. <telerik:RadAjaxManager ID="RadAjaxManagerCopyLink" runat="server">

13. <AjaxSettings>

14. <telerik:AjaxSetting AjaxControlID="RadAjaxManagerCopyLink">

15. <UpdatedControls>

16. <telerik:AjaxUpdatedControl ControlID="Hidden_LayoutID" />

17. </UpdatedControls>

18. </telerik:AjaxSetting>

19. </AjaxSettings>

20. <ClientEvents OnResponseEnd="responseEndCopyLink" />

21. </telerik:RadAjaxManager>

22.

23. <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

24. <script type="text/javascript">

25. function CopyLink()

26. {

27. $find("<%= RadAjaxManagerCopyLink.ClientID %>").ajaxRequest("TeST");

28. }

29.

30. function responseEndCopyLink(sender, eventArgs)

31. {

32. alert('<' + document.getElementById("<%=Hidden_LayoutID.ClientID %>").value + '>');

33. }

34. </script>

35. </telerik:RadCodeBlock>

36. <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

37.

38. <input type="hidden" id="Hidden_LayoutID" name="Hidden_LayoutID" runat="server" />

39.

40. <a id="Link1" runat="server" href="javascript:CopyLink();"> Create Layout Link </a><br />

41. </form>

42.</body>

43.</html>

1.Public Class _Default

2. Inherits System.Web.UI.Page

3.

4. Private Sub RadAjaxManager1_AjaxRequest(sender As Object, e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManagerCopyLink.AjaxRequest

5. Hidden_LayoutID.Value = "Hallo " & e.Argument.ToString

6. End Sub

7.End Class

All work fine, but the VB.Net code doesn't change the Hidden_LayoutID.

What went wrong?

Thanks for answers
Thomas

Hi Thomas,

Please try to attach the OnAjaxRequest event of RadAjaxManager in ASPX or code behind. Please do the following modifications in your code which works fine at my end.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManagerCopyLink" runat="server" OnAjaxRequest="RadAjaxManagerCopyLink_AjaxRequest">

...

</telerik:RadAjaxManager>

C#:

Protected Sub RadAjaxManagerCopyLink_AjaxRequest(sender As Object, e As Telerik.Web.UI.AjaxRequestEventArgs)

Hidden_LayoutID.Value = "Hallo " & e.Argument.ToString

End Sub

Let me know if you have any concern.
Thanks,
Shinu.
